Creating a group couldn't be easier. From the 'Groups' tab, click on 'Create' to set up a new group. Give your group a specific name that your kids will be able to find. Put in the start and end dates. Click on 'Create.' You will then be able to add the details for your group and put in a description and rules, if any. If you have a reading target (in minutes), you can enter it as well. Click on 'Apply changes.' You can also set up a default reward for the kids in the group (optional). When you are ready, click 'Publish'.
Once your group is published, just let your kids know how to find it. Tell them to register on Reading Rewards, and find your group in the 'Groups' tab. Once they've found it, all they need do is click on 'Join' to become a member and start tracking their reading.
